[PATCH OLK-6.6] Squashfs: fix uninit-value in squashfs_get_parent
by Long Li 25 Nov '25

25 Nov '25

From: Phillip Lougher <phillip(a)squashfs.org.uk> mainline inclusion from mainline-v6.17-rc4 commit 74058c0a9fc8b2b4d5f4a0ef7ee2cfa66a9e49cf category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ID3WGW CVE: CVE-2025-40049 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Syzkaller reports a "KMSAN: uninit-value in squashfs_get_parent" bug. This is caused by open_by_handle_at() being called with a file handle containing an invalid parent inode number. In particular the inode number is that of a symbolic link, rather than a directory. Squashfs_get_parent() gets called with that symbolic link inode, and accesses the parent member field. unsigned int parent_ino = squashfs_i(inode)->parent; Because non-directory inodes in Squashfs do not have a parent value, this is uninitialised, and this causes an uninitialised value access. The fix is to initialise parent with the invalid inode 0, which will cause an EINVAL error to be returned. Regular inodes used to share the parent field with the block_list_start field. This is removed in this commit to enable the parent field to contain the invalid inode number 0.

[PATCH OLK-6.6] media: uvcvideo: Mark invalid entities with id UVC_INVALID_ENTITY_ID
by Long Li 25 Nov '25

25 Nov '25

From: Thadeu Lima de Souza Cascardo <cascardo(a)igalia.com> mainline inclusion from mainline-v6.17-rc1 commit 0e2ee70291e64a30fe36960c85294726d34a103e category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ID2QLY CVE: CVE-2025-40016 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Per UVC 1.1+ specification 3.7.2, units and terminals must have a non-zero unique ID. ``` Each Unit and Terminal within the video function is assigned a unique identification number, the Unit ID (UID) or Terminal ID (TID), contained in the bUnitID or bTerminalID field of the descriptor. The value 0x00 is reserved for undefined ID, ``` If we add a new entity with id 0 or a duplicated ID, it will be marked as UVC_INVALID_ENTITY_ID. In a previous attempt commit 3dd075fe8ebb ("media: uvcvideo: Require entities to have a non-zero unique ID"), we ignored all the invalid units, this broke a lot of non-compatible cameras. Hopefully we are more lucky this time. This also prevents some syzkaller reproducers from triggering warnings due to a chain of entities referring to themselves. In one particular case, an Output Unit is connected to an Input Unit, both with the same ID of 1. But when looking up for the source ID of the Output Unit, that same entity is found instead of the input entity, which leads to such warnings.

[PATCH OLK-6.6] eventpoll: Fix semi-unbounded recursion
by Long Li 25 Nov '25

25 Nov '25

From: Jann Horn <jannh(a)google.com> mainline inclusion from mainline-v6.16-rc1 commit f2e467a48287c868818085aa35389a224d226732 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICU73P CVE: CVE-2025-38614 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Ensure that epoll instances can never form a graph deeper than EP_MAX_NESTS+1 links. Currently, ep_loop_check_proc() ensures that the graph is loop-free and does some recursion depth checks, but those recursion depth checks don't limit the depth of the resulting tree for two reasons: - They don't look upwards in the tree. - If there are multiple downwards paths of different lengths, only one of the paths is actually considered for the depth check since commit 28d82dc1c4ed ("epoll: limit paths"). Essentially, the current recursion depth check in ep_loop_check_proc() just serves to prevent it from recursing too deeply while checking for loops. A more thorough check is done in reverse_path_check() after the new graph edge has already been created; this checks, among other things, that no paths going upwards from any non-epoll file with a length of more than 5 edges exist. However, this check does not apply to non-epoll files. As a result, it is possible to recurse to a depth of at least roughly 500, tested on v6.15. (I am unsure if deeper recursion is possible; and this may have changed with commit 8c44dac8add7 ("eventpoll: Fix priority inversion problem").) To fix it: 1. In ep_loop_check_proc(), note the subtree depth of each visited node, and use subtree depths for the total depth calculation even when a subtree has already been visited. 2.

[PATCH OLK-6.6] kernfs: Relax constraint in draining guard

From: Michal Koutný <mkoutny(a)suse.com> mainline inclusion from mainline-v6.15-rc6 commit 071d8e4c2a3b0999a9b822e2eb8854784a350f8a category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICLGBQ CVE: CVE-2025-38282 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- The active reference lifecycle provides the break/unbreak mechanism but the active reference is not truly active after unbreak -- callers don't use it afterwards but it's important for proper pairing of kn->active counting. Assuming this mechanism is in place, the WARN check in kernfs_should_drain_open_files() is too sensitive -- it may transiently catch those (rightful) callers between kernfs_unbreak_active_protection() and kernfs_put_active() as found out by Chen Ridong: kernfs_remove_by_name_ns kernfs_get_active // active=1 __kernfs_remove // active=0x80000002 kernfs_drain ... wait_event //waiting (active == 0x80000001) kernfs_break_active_protection // active = 0x80000001 // continue kernfs_unbreak_active_protection // active = 0x80000002 ... kernfs_should_drain_open_files // warning occurs kernfs_put_active To avoid the false positives (mind panic_on_warn) remove the check altogether. (This is meant as quick fix, I think active reference break/unbreak may be simplified with larger rework.)

[PATCH OLK-6.6] nfsd: Initialize ssc before laundromat_work to prevent NULL dereference
by Li Lingfeng 25 Nov '25

25 Nov '25

stable inclusion from stable-v6.6.95 commit 5060e1a5fef184bd11d298e3f0ee920d96a23236 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICK4NH CVE: CVE-2025-38231 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit b31da62889e6d610114d81dc7a6edbcaa503fcf8 upstream. In nfs4_state_start_net(), laundromat_work may access nfsd_ssc through nfs4_laundromat -> nfsd4_ssc_expire_umount. If nfsd_ssc isn't initialized, this can cause NULL pointer dereference. Normally the delayed start of laundromat_work allows sufficient time for nfsd_ssc initialization to complete. However, when the kernel waits too long for userspace responses (e.g. in nfs4_state_start_net -> nfsd4_end_grace -> nfsd4_record_grace_done -> nfsd4_cld_grace_done -> cld_pipe_upcall -> __cld_pipe_upcall -> wait_for_completion path), the delayed work may start before nfsd_ssc initialization finishes. Fix this by moving nfsd_ssc initialization before starting laundromat_work. Fixes: f4e44b393389 ("NFSD: delay unmount source's export after inter-server copy completed.")

[PATCH OLK-6.6] init/Kconfig: Move ARCH_SUPPORTS_SCHED_SOFT_QUOTA to drop CGROUPS dependency

[PATCH OLK-6.6] nfsd: provide locking for v4_end_grace
by Li Lingfeng 25 Nov '25

25 Nov '25

From: NeilBrown <neil(a)brown.name> maillist inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/ID8DQ8 Reference: https://lore.kernel.org/all/175144911127.565058.5990359597048022103@noble.n… ------------------ Writing to v4_end_grace can race with server shutdown and result in memory being accessed after it was freed - reclaim_str_hashtbl in particularly. We cannot hold nfsd_mutex across the nfsd4_end_grace() call as that is held while client_tracking_op->init() is called and that can wait for an upcall to nfsdcltrack which can write to v4_end_grace, resulting in a deadlock. nfsd4_end_grace() is also called by the landromat work queue and this doesn't require locking as server shutdown will stop the work and wait for it before freeing anything that nfsd4_end_grace() might access. However, we must be sure that writing to v4_end_grace doesn't restart the work item after shutdown has already waited for it. For this we add a new flag protected with nn->client_lock. It is set only while it is safe to make client tracking calls, and v4_end_grace only schedules work while the flag is set with the spinlock held. So this patch adds a nfsd_net field "client_tracking_active" which is set as described. Another field "grace_end_forced", is set when v4_end_grace is written. After this is set, and providing client_tracking_active is set, the laundromat is scheduled. This "grace_end_forced" field bypasses other checks for whether the grace period has finished. This resolves a race which can result in use-after-free.

[PATCH OLK-6.6] init/Kconfig: Move ARCH_SUPPORTS_SCHED_SOFT_QUOTA to drop CGROUPS dependency

From: KaFai Wan <kafai.wan(a)linux.dev> stable inclusion from stable-v6.6.113 commit b6e9645be9eb93f7aff3ca887f8edb6f1d63358f category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ID8BLB Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… ---------------------------------------------------------------------- [ Upstream commit 4f375ade6aa9f37fd72d7a78682f639772089eed ] When unpinning a BPF hash table (htab or htab_lru) that contains internal structures (timer, workqueue, or task_work) in its values, a BUG warning is triggered: BUG: sleeping function called from invalid context at kernel/bpf/hashtab.c:244 in_atomic(): 1, irqs_disabled(): 0, non_block: 0, pid: 14, name: ksoftirqd/0 ... The issue arises from the interaction between BPF object unpinning and RCU callback mechanisms: 1. BPF object unpinning uses ->free_inode() which schedules cleanup via call_rcu(), deferring the actual freeing to an RCU callback that executes within the RCU_SOFTIRQ context. 2. During cleanup of hash tables containing internal structures, htab_map_free_internal_structs() is invoked, which includes cond_resched() or cond_resched_rcu() calls to yield the CPU during potentially long operations. However, cond_resched() or cond_resched_rcu() cannot be safely called from atomic RCU softirq context, leading to the BUG warning when attempting to reschedule. Fix this by changing from ->free_inode() to ->destroy_inode() and rename bpf_free_inode() to bpf_destroy_inode() for BPF objects (prog, map, link). This allows direct inode freeing without RCU callback scheduling, avoiding the invalid context warning.
